5.8.0 20170918 * Remove the need for NeoPixelBus library for Hue support * Consolidate WS2812 into Sonoff Led for flexible future led strip library changes * Invert WS2812 fade speed to align with Sonoff led (Speed 1 = fast, Speed 8 = slow) * Remove upper case MQTT receive buffer * Reduce code and string length for output of commands Modules and GPIOs * Add Sonoff SC debug information * Change syslog service * Removed webserver syslog disable as now no longer needed * Increased default MQTT message size from 368 to 405 bytes while keeping MQTT_MAX_PACKET_SIZE = 512 (because we can) * Fix MQTT Offline or Remove MQTT retained topic code * Fix Domoticz loop when Emulation is selected * Add blink to WS2812 and Sonoff Led (#643) * Add option WIFI_WAIT (5) to command WifiConfig to allow connection retry to same AP without restart or update flash (#772, #869) * Add support for Witty Cloud (#794) * Add GPIO14 to Sonoff Dual (#797, #839) * Add support for Yunshan Wifi Relay (#802) * Add GPIO16 input pulldown (#827) * Add timeout to DHT and DS18B20 sensors (#852) * Fix watchdog timeout caused by lack of stack space by moving to heap (#853) * Allow LogPort and MqttPort up to 65535 and add LogPort tot Status 3 (#859) * Allow command SwitchTopic in group mode (#861) * Allow command SwitchMode if no switches are defined (#861) * Add optional dimmer parameter to command Wakeup for WS2812, AiLight, Sonoff B1, Led and BN-SZ01 (#867) * Fix basic On, Off, Toggle, Blink and BlinkOff commands when other language is selected (#874)

To use I2C sensors on the Dual you need to have two free GPIO's. They are present on the ESP and solderable. I did that and customized the firmware and enabled also GPIO14.
Could you change the template for the Dual:
0, 0, 0, 0
Into:
GPIO_USER, // GPIO14 Optional sensor
0, 0, 0
I've tested both GPIO's with a DHT22 and a BME280 through I2C successful.
tele/dual_wp/SENSOR {"Time":"2017-08-27T10:20:44", "BME280":{"Temperature":26.2, "Humidity":51.2, "Pressure":1018.0}, "TempUnit":"C"}
GPIO4 => I2C SDA (red)
GPIO14 => I2C SCL (orange)
